Abstract
The present invention provides an image self-calibration method and device for LCD displays, comprising a front optical sensor and a calibration reference device. The front optical sensor is employed to calibrate the gray scale level and color temperature of the display. The calibration reference device is employed to pre-calibrate the front optical sensor. The present invention has the following advantages. Image pre-calibration is performed on the installed optical sensor before it leaves a factory, and the calibrated optical sensor directly performs gray scale level and color temperature calibration on the display. The present invention is easy to implement, can effectively inspect and calibrate images on the display, and can save human resources and reduce manufacture and maintenance time.
